Abstract: An aquarium system includes an aquarium tank arrangement and a light source. The light source has a controllable output of colored light projecting into the aquarium tank arrangement. The light source can provide a cycle of projecting light of at least two different colors.

Abstract: A nonlinear wave mixing system with grating assisted phase matching is provided. The system includes a pump laser and a nonlinear waveguide. The pump laser is used to generate pump light at a select wavelength. The nonlinear waveguide is configured to generate produced light from the pump light that is directed into the nonlinear waveguide. The nonlinear waveguide includes at least one backward grating that is configured to diffract the produced light in a backward direction relative to a direction the produced light travels in the nonlinear waveguide to reach the backward grating. The backward grating having a grating momentum that generates counter-propagating phase matching in the produced light.

Abstract: A convertible child seat has a frame assembly and a seat structure supported by the frame assembly. The seat structure defines a seating surface and is movable between at least an inclined seating position and a reclined sleeping position. A top tube assembly is coupled to a portion of the convertible child seat and is positioned above the seat structure spaced from the seating surface. The top tube assembly moves in concert with the seat structure when the seat structure is repositioned between the inclined seating position and the reclined sleeping position.

Abstract: A child swing has a frame with a base, a support extending up from the base, a hub carried by the support above the base, and a seat assembly having a swing arm with a seat carried at a lower end. The seat assembly moves in a swinging direction. The seat assembly is configured to be selectively removable from and connectable to the hub. The orientation of the seat assembly relative to the swinging direction is also selectively adjustable between a forward facing orientation and a side facing orientation.

Abstract: A child motion device has a support having an upstanding post, a seat mounted on the upstanding post, and a rotation assembly. The rotation assembly has detents carried by either the seat or the post and spaced around and radially outward from the post, and has a spring biased protrusion carried on the other of the seat and the post. The seat can be rotated to different orientations corresponding to the detent positions. The protrusion seats in one of the detents positioning the seat in a selected orientation relative to the support and determined by the detent in which it is seated.

Abstract: A multi faceted retrieval tool for use by an individual positioned above the ground in retrieving items beneath the location of the individual, comprising a series of hooks extensible beyond the periphery of the tool for engaging, securing and retrieving items which are susceptible to being engaged by a hook, and being nestable in the tool when not in use, and, further, having a magnet for the retrieval of items engageable by a magnet, and a line which is selectively extensible to engage the items to be retrieved and retractable once the item is secured to bring the item to the individual user.
